如何在 Neo4j 中删除/创建数据库? [英] How to delete/create databases in Neo4j?

问题描述

是否可以像在 MySQL 中一样在图形数据库 Neo4j 中创建/删除不同的数据库?或者，至少，如何删除现有图形的所有节点和关系以获得干净的测试设置，例如，使用类似于 rmrel 或 rm 的 shell 命令?

Is it possible to create/delete different databases in the graph database Neo4j like in MySQL? Or, at least, how to delete all nodes and relationships of an existing graph to get a clean setup for tests, e.g., using shell commands similar to rmrel or rm?

推荐答案

您可以使用 rm -rf 删除整个图形目录，因为 Neo4j 不会在此之外存储任何内容:

You can just remove the entire graph directory with rm -rf, because Neo4j is not storing anything outside that:

rm -rf data/*

此外，您当然可以遍历所有节点并删除它们的关系和节点本身，但这可能仅用于测试成本太高...

Also, you can of course iterate through all nodes and delete their relationships and the nodes themselves, but that might be too costly just for testing ...
